A client has a new prescription for metformin. Which of the following instructions should the nurse include?

Correct Answer: C

Rationale: The correct instruction for a client starting metformin is to increase fluid intake. This is crucial to prevent gastrointestinal discomfort, a common side effect of metformin. Adequate hydration can also help reduce the risk of kidney problems associated with metformin use. Choices A, B, and D are incorrect. While it's generally recommended to take metformin with food to reduce stomach upset, monitoring for signs of hypoglycemia is more relevant for other antidiabetic medications, and a metallic taste in the mouth is not a common side effect of metformin.

Correct Answer: B

Rationale: The correct answer is to monitor heart rate daily. Propranolol is a beta-blocker that can lower heart rate and blood pressure, so it is essential to monitor heart rate regularly to detect any signs of bradycardia, a potential side effect of the medication. Choice A is incorrect because propranolol can be taken with or without food. Choice C is incorrect as increasing potassium-rich foods is not specifically required with propranolol. Choice D is also incorrect as there is no need to avoid consuming dairy products with propranolol.

Correct Answer: C

Rationale: Corrected Rationale: Bradykinesia is a cardinal symptom of Parkinson's disease characterized by slowness of movement. An increase in bradykinesia may indicate a worsening of the disease and the need for adjustments in medication or other interventions. Therefore, it is crucial for the healthcare professional to report this finding to the provider promptly for further evaluation and management. Weight gain, urinary retention, and dry mouth are not directly associated with levodopa/carbidopa therapy or indicative of a worsening condition in Parkinson's disease, making them less urgent findings to report to the provider.

Correct Answer: C

Rationale: Furosemide is a loop diuretic that can lead to potassium loss, resulting in hypokalemia. Hypokalemia is a serious electrolyte imbalance that can cause various cardiac and muscular issues. Therefore, the nurse should promptly report hypokalemia to the healthcare provider for appropriate management. Choices A, B, and D are incorrect because weight gain, dry cough, and increased appetite are not typically associated with furosemide use and are not immediate concerns that require urgent reporting.
